What does MEIKO error code 15 mean?
The M-iClean U can recover heat during its cycle, and the control expects that process to finish. Message 15 is shown when the heat recovery process is cancelled before it has run to its end. It is an information message in the manual's table, not a stop condition, and no causes are listed. The manual's action is plain: allow the heat recovery process to run to completion. In practice the control reports the cancellation when something interrupts the sequence, such as the door being opened or the cycle being ended by hand, but the manual does not name those triggers, so treat them as likely and not confirmed. The display reads Heat recovery cancellation next to the number 15. Nothing in the entry says the machine is damaged or unsafe, and there is no instruction to call a technician.

Possible causes

- Door opened while heat recovery was running
- Cycle ended by hand before heat recovery finished
- A power interruption cut the sequence short
Safe checks before calling for service
- Read the message and confirm it is 15, Heat recovery cancellation.
- Close the door fully and let the machine finish its sequence without pressing cancel.
- Start the next cycle normally and watch that heat recovery completes.
- If 15 shows on every cycle, note whether it follows a door opening or appears on its own.
How a technician diagnoses error code 15
- Read the message history to see how often 15 occurs and in what cycle stage.
- Check the door switch signal for intermittent contact.
- Inspect the heat recovery unit and its sensors for fouling or loose plugs.
- Replace the part that fails testing, then run a full cycle to confirm completion.
- Door switch and heat recovery sensor tests mean working at wiring on a machine with live voltage and hot water.
- Heat recovery parts sit inside the machine housing with steam and hot surfaces.
- Diagnosing repeated cancellations depends on the machine's own message history and service settings.
